<p>给你一个字符串&nbsp;<code>s</code>&nbsp;。一个字符串的&nbsp;<strong>分数</strong>&nbsp;定义为相邻字符 <strong>ASCII</strong>&nbsp;码差值绝对值的和。</p>

<p>请你返回 <code>s</code>&nbsp;的 <strong>分数</strong>&nbsp;。</p>

<p>&nbsp;</p>

<p><strong class="example">示例 1：</strong></p>

<div class="example-block">
<p><span class="example-io"><b>输入：</b>s = "hello"</span></p>

<p><span class="example-io"><b>输出：</b>13</span></p>

<p><strong>解释：</strong></p>

<p><code>s</code>&nbsp;中字符的 <strong>ASCII </strong>码分别为：<code>'h' = 104</code>&nbsp;，<code>'e' = 101</code>&nbsp;，<code>'l' = 108</code>&nbsp;，<code>'o' = 111</code>&nbsp;。所以&nbsp;<code>s</code>&nbsp;的分数为&nbsp;<code>|104 - 101| + |101 - 108| + |108 - 108| + |108 - 111| = 3 + 7 + 0 + 3 = 13</code>&nbsp;。</p>
</div>

<p><strong class="example">示例 2：</strong></p>

<div class="example-block">
<p><span class="example-io"><b>输入：</b>s = "zaz"</span></p>

<p><span class="example-io"><b>输出：</b>50</span></p>

<p><strong>解释：</strong></p>

<p><code>s</code>&nbsp;中字符的 <strong>ASCII&nbsp;</strong>码分别为：<code>'z' = 122</code>&nbsp;，<code>'a' = 97</code>&nbsp;。所以&nbsp;<code>s</code>&nbsp;的分数为&nbsp;<code>|122 - 97| + |97 - 122| = 25 + 25 = 50</code>&nbsp;。</p>
</div>

<p>&nbsp;</p>

<p><strong>提示：</strong></p>

<ul>
	<li><code>2 &lt;= s.length &lt;= 100</code></li>
	<li><code>s</code>&nbsp;只包含小写英文字母。</li>
</ul>
